ASHA 2013 Biases in the PLS-5
With several recent graduates of the Teachers College Columbia University speech-language pathology program, we put together a poster analyzing the biases in the PLS-5. We looked at how much were based on prior knowledge including vocabulary/labeling, exposure to books, exposure to mainstream American middle-class school-oriented cultures, and the dialect of Standard American English. It was pretty shocking with only 5% of the Auditory Comprehension section and 37% of the Expressive Section qualifying as essentially non-biased. The PLS-5-Spanish reveals similiar biases.
